Grab a 15- to 20-pound body bar with your hands wider than shoulder-width apart. Rest the bar across your shoulder blades and position your legs wider than shoulder-width apart with your toes turned out. Squat until your thighs are parallel to the floor (A). Rotate your entire body 90 degrees to the left (B). Return to center, stand, and squat again, this time rotating to the right. That's one rep. Do two sets of 12 to 15, resting for 30 seconds between sets.
